The DLATR component is a level-sensitive digital register with a high enable and configurable reset and set inputs.

The strength parameter specifies a map on logic signals. Its value consists of a symbol, $S_{\mathrm{xlh}}$, with $\mathrm{xlh}$ being one of the following: $\left\{\mathrm{X01}\,\mathrm{X0H}\,\mathrm{XL1}\,\mathrm{X0Z}\,\mathrm{XZ1}\,\mathrm{WLH}\,\mathrm{WLZ}\,\mathrm{WZH}\,\mathrm{W0H}\,\mathrm{WL1}\right\}$. The three subscripts define the map:

For example, $S_{\mathrm{X0H}}$ means {X,Y,W,-} map to X, {0,L} map to 0, {1,H} map to H.

The ResetSetMap parameter is a two-dimensional, 9 by 9 array that maps the reset and set inputs to the integers 1 to 8, inclusive. The following table defines the output signal levels associated with each integer. Each symbol in a cell corresponds to an output level; the actual output level is determined by the strength parameter map.
